IMPROVEMENT iN MACHINES FOR MAKING PAPER COLLARS.

@planification forming part of Letters Patent Np. 44,871, dated .Novembi 1, 1864' To all 'whom it may concern Be it known that I, GEORGE W. LIVER- MORE, of Cambridge, in the county of Middle sex and State ot' Massachusetts, have invented a new and useful Machine for Making Paper Collars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a perspective view of my machine for making paper collars. Fig. 2 is a longitudinal vertical section throughthe saine, looking in the direction ofthe arrow x. Fig. 3is a longitudinal vertical section through the same, looking inthe direction of the arrow y. Fig. 4 is a. view of the cam-shaft F detached.

My invention consists in a new and. useful machine for making paper collars, by means of which the collar is cut from a continuous strip of paper, and the button-holes punched and the rows of imitation stitching for the next collarto be eut produced at one operation, thus` effecting a great saving in time 'and labor, and reducing the cost of manufacture.

To enable other skilled in the art te understand and use my invention, I will proceed to describe the manner in winch I have carried it out.v

ln the said drawings, A is the frame-work, in suitable bearings, in which runs the driving-shaft B, to which is secured the'iiy-wheel C. rl`his shaft carriesthe gear D, which engages with the gear E on a sli-att, F, having its bearings in the framework. lo each end of this shaft F is secured a crank, a, which is connected with the frame or carriage G by means of a pitmau, b. This frame moves up and down in suitable ways inthe standards c d, and has attached to its under side a solid die or cutter, e, ofthe form of the collar to be cut, and three punches,j`, for cutting out the button-holes. The die e and punches fin their descent pass through suitable holesin a presscr-plate or clearer, g, (the under side `of which is covered with india-rubber or other elastic material,) and into holes in a bed or table, h., which are made of the exact size to receive them, and torni the under dies.

I will now proceed to describe the manner in which the strip of paper from which the collar is to he cut is fed under the die or cutter.

.Il is a table,through slots in which project the rods i j, which are secured at their lower ends to a shaft, I, which is rocked by means of a rod, it, to which is pivoted a rod, l, which is moved in one direction by a cam, 5, on the shaft F, and in thc opposite direction by the Spring m. To these rods i j are pivoted the rods u o, to the former of which is attached the upperjaw, p, and to the latter the lower jaw, q, of a pair of nippers. The lower jaw, q, plays in a transverse slot in the table H, and its upper edge is flush with the surface of this table. Ir s are two bent rods, theupper extremities of which are enlarged and pass up through the table H, and are forked so as to embrace the rods n and admit the frictionrolls (5. The lower extremities of these rods r s are pivoted to arms t u, projecting from a shaft, J, (having its bearin gs in the frame work,) which is rocked by means of an arm, e, Fig. 3, which is raised by means ot' a cam, w, on the shaft F, against the resistance ot' a spring, e', so as to raise therods n and open the nippers.

b b are two levers which are pivoted tothe shaft- J, and are raised against the resistance of springs c by means of cams d on the shaft F. To these levers are pivoted the arms c', which are made adjustable in length bymeans of screws and slots in the ordinary manner. The upper ends of these arms e are bent over and attached to the clearer g, so that as they are depressed it will be brought down onto the table h. to hold the paper and keep it perfectly smooth. while it is being cut. Y The clearer g also serves to throw the paper olf from the upper die, e, and punches f as they rise after the cut is made.

j" j" are two spring-levers pivoted to uprights projecting from the table H, their longer arms being connected together by a rod or roller, g', that rests on the rods oz. of the nippers, their shorter arms resting on the bent ends of the arms e', by which means, as the presser-plate or clearer g is raised, the rod g is forced down onto the rods c, thus closing the nippers onto the strip of paper. The nippers are then carried forward by the vibration ofthe rods i j, and the paper is fed in the required distance. ()ne or more rows of steel points, 7, projectup from the table h in advance of the lower dies, which form the button-holes, so' that as the paper is pressed down onto the t.\blc h by the clearer g, with its elastic surface, the imitation stitching will be produced around the edge of the collar as required, the button-holes being cutandthe stitching produced in the paper before the collar is ent out by the die e, and any other device besides the imitation, stitching maybe stamped on the collar at the same time by the descent of the clearer g, suitable dies being provided for the purpose.

t" is a flat strip of metal, which projects (while the paper is being fed in) nearly over the hole or under die in the table h, which corresponds to the form of the cutter e, so as to form a guide and prevent the paper from striking the edge of the lower die. This strip 'i' is withdrawn out of the way, before the die e descends, by the following device:

K is a shaft having its bearing in the framework from which rise the rods j', which are connected together at their upper ends by a rod, k', to which the strip i is secured.

l is a rod projecting down from the shaft K, to which is pivoted the rod m. This rod is bent over at its opposi te end, and is carried in one direction by a cam, n', Fig. 4, on the shaft F against the resistance of a spring, o',

by which it is retracted, and thus, as the shaft- K is rocked, the strip t" will be carried forward and back at the required times. The rods j and l pass through holes in the shaft K, and are made adjustable therein by means of screws 8, and the shaft K is made adjustable in vertical slots'in the frame-work, by mea-ns of which adjustments the throw ofthe strip 'i' can be varied, as desired.- The amgount of motion of the feed-nippers can also be varied in a similar manner, the shaft I being made adjustable in vertical slots in the frame-work andthe rods i j passing through holes in the shaft I, where they are secured in place by screws 9.

The upper die, e, and punches f may be adjusted exactly with respect to the lower dies by means of screws and slots and wedges in the frame or carriage G, and the pitmen b are made in two pieces, which are joined together by screw-connections 10, by which means their length can be varied, as desired. The several cams en the shaft F are also made adjustable by means of set-screws in a well known manner.

The pins 7,'instead of projecting up from the table h, may project down from the presser-plate g, if desired, a portion ot the table h beneath them being made elastic.

In the abovedescribed machine I am enabled to use a continuous strip of paper, instead of using sheets, as heretofore, thus preventing a great waste ef material and greatly facilitating the process cf manufacture.

Operation: The machine being set in operation, the end of alongstrip ofpaper is fed into the nippersp q. The clearer gis then raised by the arms e', as explained, causing the springlevers j" to press the rod g onto the rods n and close the nippers onto the paper. The, shaft I is now rocked by the rod k, as before explained, which causes the rods 'j to carry forward the nippers with the paper the required distance, the paper passing between the clearer g and the table h and being guided i across the lower die by the metallic strip t',

which extends .nearl y across the opening. The clearer g is now brought down and holds thel paper firmly onto the table h and presses the steel points into the paper, to produce the imitation stitching. The die e and punches f now descend, (the strip t" having been with drawn by the rocking of the shaft k, as before eXpla-ined,) cutting out a collar andl punching the button-holes for the next collar to be cut. While this is taking place the rods n are raised by the forked rods r s, (the pressure of the friction rod glhaving been relieved by the descent of the clearer,) thus opening the nip-` pers, which are then carried back over the paper by the vibration ot' the rods ij, to take a fresh hold, as already described. Thedie e and punches j' now ascend, the clearer g serving to throw the paper oii and keep them clear. The clegrerg is now raised off the table h, to allow the paper to becarried forward by the nippers, the strip t" is carried forwardover the lower die, and the operation continues as before, a collar being cut out and the button-holes and the imitation stitching produced on the paper for the ne'xt collar to be cut at each'operation of the machine.

The collar, after it is cut, passes through the table h into a trough, L, by which it is carried out of the machine.

I do not confine myself to the precise details of construction here described, as it is evident that these maybe varied to a considerable extent without departing from the spirit of my invention.

What I cla-im as my invention, and desire to secure by Letters Patent, is4

The feeding-nippers p q, in combination with the cutting-out dies, the presser-plate a, and table h, operating substantially as set forth, for the purpose specified.
